dc.descriptionOil shale from Elko (Nev.) was pyrolyzed in a partial vacuum, and the products were examined. Retorting in a partial vacuum reduced the amount of cracking and increased the oil yield; the first drop of light oil appeared at 192/sup 0/C and the first drop of semisolid bitumen appeared at 232/sup 0/C. Oil-shale kerogen from Elko (Nev.) appeared to be a polymerized product of montan wax, which, upon thermal decomposition, depolymerized into primary bitumen and finally into secondary products. Heptocosane (C/sub 27/H/sub 56/) was extracted from the primary bitumen.
